Answer: 30 = y
Step-by-step explanation: When we have two sets of directly related coordinates, x₁ and y₁, and x₂ an y₂, we can use the ratio below to find the missing value.
y₁ / x₁ = y₂ / x₂
We know that y = 24 when x = 8.
So one set of coordinates will be 24 and 8.
We want to know the value of y when x = 10.
So the other coordinates will be y and 10.
So we have 24/8 = y/10.
Now, we can solve for y using cross products.
So we have (24)(10) which is 240 and (8)(y) is 8y.
So we have 240 = 8y.
Now dividing both sides by 8, we have 30 = y.
So 30 is equal to y.
